Petrol in a Diesel Car in Greave
If you have not fired up the motor yet, do not. A fuel drain and nothing else is almost always what a motor requires while the petrol is still in that tank and the engine has not been started, which is why it is the coming few minutes that count, not how much was put in. Petrol in Diesel goes to your car wherever it has come to rest in Greave or the rest of Lancashire, on the forecourt, at the roadside or on a drive, and drains and cleans it there. Ring us and our technicians can tell you what follows after that before you attempt anything else.
What to do next about petrol in a diesel
- Feed a petrol motor diesel and it will generally fail to run at all, and so the person stops there and so does the harm. Feed a diesel petrol and the thing starts, it idles, it moves off — fine enough for a few miles. Most people have that muddled, which is the bit they get wrong about petrol in a diesel especially. So never fire it up. And once started, never depend on it: that fuel system is grinding while you drive.
- Switching your ignition on frequently primes the system, and priming is what draws petrol out of your tank then into your pump and injectors. Those are the parts diesel keeps lubricated on its way through, before it combusts. Petrol does the burning and none of the protecting. Leave your ignition off.
- That guidance supposes a diesel fuel system copes with petrol by percentage. It won't. Pour diesel on top and nothing at all is removed; what you have is a bigger tank of the same blend. And no, the octane makes no difference — super unleaded is simply petrol.
- Wait where you are if you reasonably can. A car that has never moved is the easiest one to sort, and we'd much rather travel to a difficult spot than have it started. If you are parked on the verge on Nuttall Street, turn your hazards on and keep it there.
- Before you phone, get your position. Anything nearest to you with a name on it, plus a postcode beginning OL13 9 — that's what determines whether the technician shows up or circles.
- Three facts shape the entire call-out: the liquid you poured in, the approximate amount involved, plus whether anything has been running since. The line is 0333 366 0103.
Do not take it home. Petrol-thinned diesel has passed through that high-pressure fuel pump in real volume on the way in, and the way back would more or less double that for nothing at all. Ring us — the platform is good. There's no need to stand over that Renault Clio outside Walsden while the work gets done, and we would far rather talk to you tonight than find out on Monday.
A diesel pump supplies fuel on demand, and a rushed morning drive asks for plenty — so three miles in the Peugeot 308 feels like nothing and is not. Twenty to nine outside St Mary's Roman Catholic Primary School, a Voluntary Academy, already late, a receipt in your hand reading unleaded: hazards on, ignition off, ring us.
Seldom the problem, the location. On-street is the usual spot we work, and a tight parking bay is far preferable to a vehicle that has been driven somewhere more handy. What does help, when you call from close to Bacup Christ Church, is three things: the side the filler is on, whether our van can park alongside without blocking the road, and if anything has run since you filled up. Then your Dacia Duster gets emptied, the filter changed where a usable one exists, the fuel lines rinsed and fresh fuel put through the entire circuit — as by now the worst of that is in your lines, not that tank.
Clattering, a ragged idle, white smoke, a throttle gone dead. That's a misfuelled diesel BMW 1 Series telling you what is wrong. Switch off where you have stopped, near Christ Church with St John or anywhere else, and don't start it to find a better location.
What happens next is the problem. Your engine straight away sucks the petrol still sitting in your filter and the feed lines back round through your pump a second time, because emptying a tank does nothing about fuel that has already left it. Drain it and put clean diesel in, someone confident will tell you — and that suggestion is half true, as do it to a diesel Kia Sportage parked up, Broadclough Dykes say, and the thing starts, which is what makes it sound sensible. Ring us instead. We flush your circuit and take your filter off where the car has a serviceable one, and that is the difference between the vehicle being fixed and your car only starting.
Clearing petrol from the diesel at a forecourt
Much of this work starts at a forecourt, meaning a good share of that gets completed there. Still at Texaco? Then that's usually where it gets done. Garage forecourts are routine for us, with the agreement of the station.
At a garage, this is spotted with the motor never started, and no place else manages it. The few seconds between seeing the receipt and reaching for your key determine how much requires flushing. Anywhere other than a forecourt — a car park, a private drive, a lay-by — the car was fired up and moved to get there, so fuel was pulled from your tank, through the fuel filter then into your high-pressure pump. That means your lines and the fuel filter need rinsing as well as your tank. It is not a disaster, and our technicians can still deal with it where your car sits.
Wheel the car out of the way if the attendants volunteer, and they usually will. The next customer gets through the pump, and that is worth doing. Moving it four bays does not justify cranking it.
Do our engineers cover your side of Greave?
These same journeys carry us to Higher Change, Lane Head, Bacup, Broad Clough and Sharneyford besides Greave, which is a residential suburb.
If yours isn't on that list it does not mean we do not come — there are separate pages for the majority of locations across Lancashire, and the ones named above are merely the closest neighbours. Assuming is the habit to skip, above all on the boundary or anywhere your phone struggles. Contact us and ask.
The patch this page spans is on this map. Our technicians work by the road, at forecourts, on driveways and at car parks throughout all of that, and your vehicle doesn't need to come to us.
Kerbside call-outs around Greave
Not everyone finds a decent spot to pull over. If you worked it out after setting off and finished up along the verge beside Oakenclough Road, or in a lay-by somewhere with the hazards flashing, that's a common call for us instead of an odd one.
Whether you wait beside the car or move away from it turns on whether being nearby looks wise. Never start up the motor to nurse the car somewhere better — a diesel running on petrol will frequently oblige, and every mile it obliges for is pulling that mixture further into your fuel system. Carrying on causes your car far more harm than a technician driving out to an awkward spot, and that is no trouble for us.
Driven it already? Stop, then read below
The M66 is the road that counts now, and it sits under 10 miles from Greave. Some distance along, and onto it in the first place: a misfuelled diesel will usually do both before anything seems wrong. What you get then is seldom a clean stop. Power drains away, your idle turns uneven, and there may be smoke.
The next sensible exit is the one to take. Switch off there, and leave the restarting alone. Presume the worst of it on a long drive. Anything approaching the under 25 miles to the nearest city, and the mixture has been through your filter, through your pump, through the injectors. Tell us when you ring. What our technicians bring changes.
About Greave
Greave is a suburban area in Lancashire, situated on the riverside with a mix of terraced housing and other residential properties. Greave sits at an elevation of 290 metres, overlooking the surrounding landscape. Greave is located near several other small communities, including Higher Change, Lane Head, and Bacup, and is within commuting distance of Manchester, which is approximately 16 miles away.
What our technicians do when we get to you around Greave
- We ask first, price after. What was put in? How much? Has the engine run? Those answers alter what the work really is.
- The tank gets drained of it.
- Lines flushed, filter cleaned. Whatever remains later is not the thing that started the trouble.
- The system gets bled, on clean diesel.
- Our engineers fire it up and make sure it runs smoothly on fresh diesel.
The car is then ready for you to pull away. All of it is done where the vehicle is, so it never needs to be taken to a workshop, and when it has been caught soon, long-term damage is very uncommon.
AdBlue in a diesel tank around Greave is a distinct job
If what got in was AdBlue rather than petrol, the opening rule is unchanged — don't crank it — but this issue isn't. The protection a fuel system relies on gets stripped away by petrol, which weakens your diesel. Corrosion and residue are what a diesel tank ends up with instead, because AdBlue is urea dissolved in water.
Our technicians deal with both, and AdBlue removal around Greave has its own page with the full story — including why it is often the more serious of the two.
What a petrol-in-diesel drain costs in Greave
We cannot put one price on this page truthfully, because this job is not one job. What changes it:
- Has it been run or driven? Nothing else counts for as much.
- The tank's capacity, set against how much of the wrong fuel went into it.
- Whether it's unleaded or AdBlue.
- Where the vehicle is, and whether our van can safely get to and work on it.
Tell us what the vehicle is, how much got in, and if the engine has run. A straight answer comes back, not a range. If it's not urgent — your car is at home and going nowhere — is fine too.
Questions our technicians hear about petrol in diesel around Greave
Can you do a fuel drain at a petrol station around Greave?
Much of what our technicians do happens nowhere else. So yes. Agreement from the site is the condition. Given that, a forecourt like Shell is somewhere we're frequently, along with the rest of them locally — so name yours on the phone and you will hear if working there's possible.
How much petrol is too much for a diesel?
Ratio settles it instead of litres — and more than either, whether the engine has run. What determines how much work is needed is if that mix has been sucked through your fuel system — since although five litres in a nearly empty tank is a separate situation from five in a full one, either way that's the question.
I drove the car after putting petrol in my diesel. What next?
Pull in somewhere safe, turn off, and keep it off. It is fixable far more commonly than motorists fear, even though driving is what takes the trouble from your tank into your pump and injectors — and the single most valuable thing you can do now is not restart it.
Fuel drains and manufacturer warranties
No. Carried out correctly, draining and purging is no alteration at all, and the warranty from your manufacturer is untouched by it. An argument over a warranty is likelier to come from running a diesel on petrol — so leave it turned off.
Adding two-stroke oil, then driving home
No. Two-stroke oil is an old workaround for a separate issue and it doesn't replace what petrol has thinned. Afterwards? Still petrol in the tank, and a pump that has to cope with the stuff.
Do I need a main dealer for petrol in a diesel?
Wherever the car is, we drain and clean it there, so a trip to the main dealer does not come into it.
Is your car still with you?
The engine stays off.
Driven it already? Then somewhere safe, stop, turn off, and no restarting the vehicle afterwards. Cold and still, a vehicle is in the best place available — and drivers fear this a lot more than the recovery rate warrants.
